Minimal required features for the Project Pythia landing page

[brian-rose]

Since this repo houses the experimental source for a potential new landing page / web site for Project Pythia, let's track here the missing features from our existing Sphinx-based home page that are considered essential before migrating to MyST-MD.

We are comparing this new landing page to the existing landing page.

I'll take a first stab at a minimal feature list:

• Landing page is clean and simple and less "bookish"
• A branded banner image
• "call to action" buttons are appropriately sized and styled
• Pythia google calendar is displayed
• Footer with essential credits
• Blog posts are easily findable
• Admonitions display properly, e.g. on the Contributor guide page
• Metrics page is properly populated
• Code of Conduct page is findable
• All remaining "Unknown Directive" errors are cleaned up

What else? What did I miss?

There is some overlap here with the checklist over at jupyter-book/mystmd#1320 (comment), but I'm trying to keep this list specific to the main "portal" site and landing page.

Looks pretty complete to me, @brian-rose
